Transfer solid waste more efficiently with a versatile SSI pre-load compaction system. SSI’s ruggedly constructed compactors consistently deliver the maximum legal payload day in and day out. High density solid waste compaction produces clean, efficient transfer to highway trailers as well as intermodal rail and barge containers. SSI compaction systems are large self-contained units that compact material within the compression chamber¬-independent of a transport vehicle. No trailer damage! So, use lighter weight transport equipment to achieve greater payloads.
